Super Sealed Units is the specialized double-glazed glass unit division within the Super Toughened Glass Group, a glass processing specialist in the UK with a strong reputation for fine quality and top customer service. 


The company focuses on all sizes of insulating glass units (IGUs) for domestic and commercial customers.

The group started with IGU production in 2011, when it bought the entire business from another company, including the original Glaston ProE furnace dating from 2001.

With growing demands in our market, we needed to bring our older Glaston furnace up to modern standards. Thanks to the installation done over Christmas break, we were able to save time – to get up and running quickly at the start of the year.


Says Sanjay Meghani, Director, at Super Sealed Units Ltd in Dunstable, UK. 

Today, we are able to temper higher performance glass, achieve flatter results and utilize the full furnace bed for greater volumes.


We had recently been facing issues when loading glass across the full bed of our furnace.
We could not keep the heating consistent across the chamber. We needed a way to produce flatter glass and gain greater control of the heating across all areas of the bed. It was clear that we needed to bring our older furnace up to modern standards to meet growing demands.


NEW FURNACE OR UPGRADE?

Super Sealed Units and the entire Super Toughened Glass Group have always had Glaston furnaces and glass processing equipment.

When the teams were discussing the problems they faced, the two options were either to replace the furnace with a completely new one or to upgrade the existing furnace with a Roller Heat Control (RHC) modernization. This upgrade eliminates problems caused specifically by roller heat disturbances and increases overall glass quality.

The new furnace would have cost more. But, even more important than the money aspect, was the fact that a new furnace would require about two months of work: one month to remove the existing furnace and a second month to install the new one.


Sanjay explains.

A HOLIDAY INSTALLATION


The senior management of Super Sealed Units decided to move forward with the RHC upgrade in September 2017.

For us, the RHC was an optimal way to save time. And by scheduling the installation over the Christmas break, when volumes tend to be lower and the company is closed for two weeks in any case, we were only inconvenienced for a period of about two weeks or so. We were pleased that Glaston was willing to work over the holidays. And we did as much preparation work as possible beforehand so that the Glaston team could do their part without us being in their way.


He says.

The Group’s Park Royal facility provided the toughened glass that Super Sealed Units needed to deliver for their customers while the furnace was out of commission.

TRAINING DURING PRODUCTION

Scheduled for the second week in January, training for Super Sealed’s five operators took about a week and a half.


Since everything was very similar to what we already use from Glaston, the training was quite straightforward. Our operators already have a good basic knowledge of using the furnace. Once the new control panels were installed, it was easy for our operators to start using them.


Sanjay says. 

We actually carried out the training at the same time as the machine came back in production. 

This was beneficial for us so that we could smoothly continue with our deliveries to customers.
